UploadBillFile

Attaches one file to a bill of the API key’s supplier and company. A bill needs at least one file before it can be submitted. The file is visible to the company and to the supplier in the portal. How keys and responses work is on Vendor bills.

Send the request as multipart/form-data with two parts: BillID and the file.

POST /api/public/uploadbillfile
APIKey: your-api-key
Content-Type: multipart/form-data; boundary=...

For example, with curl:

Terminal window
curl -H "APIKey: your-api-key" -F "BillID=109827" -F "file=@INV-2026-0042.pdf" https://trakit.example.com/api/public/uploadbillfile

Replace https://trakit.example.com with your TrakIT address. Send one file per request; to attach several, send several requests.
